My new keyboard arrived, and I like it a lot. The keys have a nice tactile feel on keypress, and I’m not making nearly as many typos as I was on my last two keyboards. My fingers just “know” where the right keys are on this one.
This particular keyboard has one particular feature that I really like: The alternate characters (such as ®, ©, ‡, ¶, and others that aren’t accessed via regular keys) are printed right on the face of the keys, so it’s easy to find the particular one I’m looking for, and I can type them by simply hitting option-key or option-shift-key.
There were two keys that were problematic on this keyboard, though. The caps-lock key has been moved from its normal home on the far left of the keyboard, above the shift key, over to the right side of the bottom row, between the option and control keys. I found that I was frequently hitting caps-lock instead of option. The Mac’s System Preferences -> keyboard modification allowed me to change that mapping, and now my caps-lock key acts liks the option key. I virtually never use caps-lock, so this is a perfectly acceptable solution.
The other problem was, the help and delete keys are lower than I’m used to, and so I was frequently hitting help when I was reaching for delete. Which opens the help viewer, which I then have to close, and then I can delete whatever I trying to delete. The built-in keymapping options didn’t allow me to change that, but a little freeware program called Ukulele solved that problem handily. Now my help key acts like a second delete key, and it doesn’t matter which of those two keys I hit. I rarely use the help files, and when I do I usually access them from the menu using the mouse, so that also is a perfectly fine solution.

Now that I’ve found a keyboard I like, I’m thinking I should order a lifetime supply. I’m quite sure they’ll stop making it.
